IMPROVEMENT IN METHODS OF PROTECTING EMERV-WHEELS.

Specification forming part of Letters Patent No. 193,806, dated July 17,1877; application filed May 28, 1877.

To all whom et may concern:

Be it known that I, WILLIAM W. WHITE, in the county of McKean and Stateof Pennsylvania, have invented a new and improved Inode of preventingemery-wheels and emerygrindstones from glazing, breaking, or burstingwhile gumming, grinding, or cutting away the steel; and I do herebydeclare that the following is a full and exact description thereof.

My invention consists in applying ice to the emery-wheels oremery-grinders while being used to grind or cut away the steel.

One mode of application is to place the ice on the steel to be cut awayand let the ice rest against the emery-stone a-t the saine time.

My invention .also consists in applying ice at one and the saine time toboth the wheel and the metal while the metal is being ground.

In the drawings, Figures l and 4 represent a mode ofapplyingice in thegumming ofa saw. rIhe ice rests upon the saw B and against theemery-stone A, and is held in position by the tool D in the hand ot' theworkman, or otherwise steadied. Here the described eiiects are producedon both wheel and saw.

Fig. 2 represents the ice C resting against the stone A while a chiselis being ground, the ice adording its coolness and its moisture directlyto the stone alone with the eiiectabove described.

Figs. 3 and 5 show a mode of applying ice in the grinding of aplaner-knife, where the ice C rests upon the knife, and not against thestone, and is held in position by the tool D. The ice may also be soplaced as to be held in position by its own gravity.

My discovery and its mode of application may bernore fully understood byreference to the accompanying drawings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The method of preventing emery-wheels from glazing, breaking, orbursting while being used, which consists in applying ice to the wheelwhile it is in operation, as set forth.

2. The method of preventing emery-wheels from glazing, breaking, orbursting While being used, and of preventing the metal .being groundfrom changing in quality, as described, which consists in applying iceto the Wheel and to the metal being ground, as set forth.
